Farm is the place where your captured monsters are stored automatically. The limit of each farm is 20 monsters. There is a button which you could press to return back to farm from any place and change your monsters (on the task bar). The maximum of monsters available in your task bar is 6 at a time. You can rest your monsters to restore its health and other attacking stats. Once you exceeded the limit of your farm, you can buy another one using your bulu points (costs 100 points).
